+### Get the most from your queries
+
+Elastic AI Assistant helps you take full advantage of the {elastic-sec} platform to improve your security operations. Its ability to assist you depends on the specificity and detail of your questions. The more context and detail you provide, the more tailored and useful its responses will be. 
+
+To maximize its usefulness, consider using more detailed prompts or asking for additional information. For instance, after asking for an {esql} query example, you could ask a follow-up question like, “Could you give me some other examples?” You can also ask for clarification or further exposition, for example "Please provide comments explaining the query you just gave."
+
+In addition to practical advice, AI Assistant can offer conceptual advice, tips, and best practices for enhancing your security measures. You can ask it, for example:
+
+* “How do I set up a {ml} job in {elastic-sec} to detect anomalies in network traffic volume over time?”
+* “I need to monitor for unusual file creation patterns that could indicate ransomware activity. How would I construct this query using EQL?”
